In the last decade, the development of on-site field laboratories to measure water chemistry at sub-hourly measurement intervals has drastically advanced, while there is no literature that provides detailed technical, organisational and operational guidelines in running such equipment. Based on our experiences of running three French field laboratories over 7 years, we share the main stages in the deployment of this tool in the field, the difficulties encountered and the proposed solutions.

In 2022, France faced its driest year on record, severely affecting the forests of the Strengbach catchment. We observed unusual chemical changes in the soil, linked to drought stress. These included nutrient loss, soil acidification, and stress of soil organisms. Our findings show how drought harms soil health, especially in forests already lacking nutrients, and help predict how ecosystems may respond to future climate extremes.

To increase the predictive power of hydrological models, it is necessary to improve their consistency, i.e. their physical realism, which is measured by the ability of the model to reproduce observed system dynamics. Using a model to represent the dynamics of water and nitrate and dissolved organic carbon concentrations in an agricultural catchment, we showed that using solute-concentration data for calibration is useful to improve the hydrological consistency of the model.

Short summary
The potential of constructed wetland to remove nitrate and pesticides increases with the residence time. The aim of this work is to investigate how the hydraulic performance changes with the flow rate in a party vegetated wetland, using the 3D hydrodynamic model. It was calibrated on continuous outflow concentration and tracing experiment. The simulation matched satisfactorily with observation. Results showed a limited increase of the hydraulic performance with the flow rate.

Through a river cross-section, we show that fluvial organic carbon in the lower Huanghe has clear vertical and lateral heterogeneity in elemental and isotopic signals. Bank erosion supplies terrestrial organic carbon to the fluvial transport. Physical erosion of aged and refractory organic carbon, including radiocarbon-dead organic carbon source from the biosphere, from relatively deep soil horizons of the Chinese Loess Plateau contributes to fluvial particulate organic carbon in the Huanghe.

Short summary
Lumped conceptual groundwater transit time models are widely used for their computational simplicity. But their parameters being empirical, these models are often criticized for their calibration reliance. This study mathematically links lumped conceptual parameters to measurable hydrodynamic properties of a groundwater catchment. This kind of direct parameterization gives lumped models a forward modelling potential, and also improves the choice of parameter constraints in calibration exercises.

Groundwater discharge into streams plays a major role in the preservation of stream ecosystems. There were two complementary methods, both based on the use of the distributed temperature sensing technology, applied in a headwater catchment. Measurements allowed us to characterize the spatial and temporal patterns of groundwater discharge and quantify groundwater inflows into the stream, opening very promising perspectives for a novel characterization of the groundwater–stream interface.

The hydrological subsurface drainage model SIDRA-RU is assessed at the French national scale, using a unique database representing the large majority of the French drained areas. The model is evaluated following its capacity to simulate the drainage discharge variability and the annual drained water balance. Eventually, the temporal robustness of SIDRA-RU is assessed to demonstrate the utility of this model as a long-term management tool.

This study investigates the drivers of spatial variations in stream water quality in poorly studied headwater catchments and includes multiple elements involved in major water quality issues, such as eutrophication. We used a regional public dataset of monthly stream water concentrations monitored for 10 years over 185 agricultural catchments. We found a spatial and seasonal opposition between carbon and nitrogen concentrations, while phosphorus concentrations showed another spatial pattern.

Short summary
The abundance and isotope composition of the trace metal barium (Ba) allows us to track and quantify nutrient cycling throughout the Amazon Basin. In particular, we show that the Ba biological fingerprint evolves from that of a strong net nutrient uptake in the mountainous area of the Andes towards efficient nutrient recycling on the plains of the Lower Amazon. Our study highlights the fact that the geochemical signature of rock-derived nutrients transported by the Amazon is scarred by life.

Short summary
The proposed methodology consists of simultaneously analysing the concentration variation of solute pairs during a storm event by plotting the concentration variation of one solute against the variation of another solute. This can reveal whether two or more end-members contribute to streamflow during a storm event. Furthermore, the variation of the solute ratios during the events can indicate which catchment processes are dominant and which are negligible.
